KNX Status Groupadress does not work as expected

[GoogleCodeExporter]

KNX Hardware: PEAR-PA-21S-230-16-1RM

Group Adresses: 
1/2/0 Lamp On/Off
1/2/1 Lamp Timefunction (600s ON)
1/2/4 Lamp On/Off Status

The presence detectors activate the Time Function. The Power Actor reports on 
the Status Adress if the channel is on or off.

I tried a lot of possibilities in the default.item file, currently i use:
Switch Light_EG_Living_Stehlampe    "Stehlampe"     (EG_Wohn, Licht)  { 
knx="1/2/0+1/2/4" }

The Status of the Actor is not detected at Startup, the Lamps have to be turned 
off and on so the Status is correct.

Did i misuse the configuration? Is their a workaround?

BTW. Thank you for the Software, i like it a lot so far :)

From what I understand, the only thing that is not working for you is reading 
the status at startup.

For this, you simply have to add the information that a KNX read request should 
be sent at startup, i.e. { knx="<1/2/0+1/2/4" }.

When i use the Syntax as you wrote it ( { knx="<1/2/0+1/2/4" } ), then i get 
the following errors :

OpenHab:
00:32:59.024 WARN  o.o.b.k.i.bus.KNXBinding[:461] - Cannot read value for item '
Light_EG_Living_Stehlampe' from KNX bus: timeout waiting for group read response

In the ETS4 Groupmonitor around the same time, i will see a read request on 
1/2/0 and not  as expected on 1/2/4

That is the expected behavior, read requests are always done on the command GA. 
Make sure that your have set the "r" flag in your ETS for this GA.

Hi Kai,

I did some initial tests with KNX and openHAB yesterday and would have also 
expected to be able to do something like { knx="1/2/0+<1/2/4" } to read from 
the e.g. status object. Most KNX actuators have status objects which show the 
real state of the channel (the Command GA could have been e.g. blocked).

Do you see any technical or design issues with "<" on listening GAs? I should 
be able to provide a fix for this if it is just a matter of parsing the 
configuration string.

Thank you.

Cyril

Hi Cyril, 
You are right, it should also be possible to read at startup from status GAs. 
Not sure if enhancing the parsing bit is enough or if it will require further 
work. Feel free to try it yourself and provide a changeset in a clone later on.

Cheers,
Kai

Cheers, will do after releasing 1.1 - too risky otherwise!

Hi Cyril,
thank you very much for implementing this fix. I had exactly the same issue.
After checking it out from your repository I tried it a little bit and it 
really works well. I will keep it running on my home server while extending my 
home automation system.
